This two-in-one air conditioner for both refrigerator cabinet is the shared compressor of frequency control, signal indication control is based on air-conditioning CPU indoor set, refrigeration working medium is tentative to be R22, based on operation of air conditioner, appearance structure is based on refrigerator, refrigerator is a ★ ★ ★ level, and the dual-purpose two-speed is practical patent, and WU formula air conditioner for both refrigerator cabinet is a patent of invention.And based on the PANASONIC product, this product " raw material ", " fine finishining " are with reference to the refrigerating operaton of Japanese industry JIS: condition (indoor 27 ℃ of DB/19.5 ℃ of WB, outdoor 35 ℃ of BD/24 ℃ of WB) join 7 mitrons, heating installation overload operation indoor (24 ℃ of DB, outdoor 21 ℃ of DB/15.5WB) condition.It combines with refrigerator Intelligent Fuzzy Control single-chip microcomputer 87C552.It is applicable to " two-in-one ", uses in the air-cooled air conditioner.

Its adopts LED, LCD to show, is divided into being the houshold refrigerator formula below 2, and the fixed and fixing single open-door not of one drag two is arranged.The clamshell doors refrigerator cold-storage multi-functional air conditioner that more than 2 is restaurant, office building, meeting room is for fixing split type.

The air conditioner for both refrigerator cabinet (claims 2﹠amp again; 1 air-conditioning cabinet, the application in automobile: utilize the air-conditioning of automobile itself to load onto, two chambeies, one gas compressor, before paying operator seat, automobile repacks a small-sized refrigerator into, can enjoy at an easy rate, make tired thirsty driver's relieving fatigue and sleepiness, can be to increasing some enjoyment and sentiment on the automobile.Its duty be the driver stop leave car body after, in two hours＜adjustable finish automatically, turn-off the refrigerator power supply at last, the refrigerator electricity is not controlled by its automobilism power remove.

Be the 8125W air-conditioning with 3 refrigerating capacitys of music below, 66 page fixing formulas of European popular multifunctional refrigerating bin refrigerator clamshell doors of 484 liters of 400W are example.Particularly in portable two-in-one the reservation outside the existing various functions of air-conditioning refrigerator, also increased family's thawed foodstuff function commonly used and need not electrical heating defrost function, this considers often to need thawed foodstuff winter in the north, and does not need microwave food just can thaw and design.And the heat that heats working medium of utilization itself simply, also consider difficult sleeping characteristics in summer in addition, and the design hypnosis function, adopt the unique function of the hypnosis that Wen Yusheng, the upright fork of gas match.

First state is the refrigerator running status, indicator lamp bright (blueness) when (referring to summary figure) refrigerator run signal enters in the air-conditioning control room mainboard, compressor operating, bright 2 of power output indicator lamp, refrigerator electrical adjustment valve (W1) 17 is opened, and the refrigeration working medium HTHP moves towards refrigerator (annotate: refrigerator independent operating outdoor fan does not change) from outdoor condenser to (W1) 17.Flow to refrigerating chamber 9 through cold compartment of refrigerator 11, flow to pipe 22, enter cross valve W3 through the refrigerator low pressure mouth of pipe 18, inflow pipe 21 enters separator again.This moment, refrigerator was 30HZ, 400W output.When air-conditioning added operation at this moment, another entered CPU by the operation of air conditioner signal, and CPU just quickens compressor according to instruction repertorie, connected the outdoor fan operation.Operation of air conditioner indicator lamp bright (redness), the power output indicator rises to 9 by 2, see Fig. 7, air conditioner electronic control valve W52 opens entirely, the rotating speed of compressor is consistent with opening of valve W5, compressor is sent to outdoor condenser to the HTHP refrigeration working medium and flows to the room evaporimeter behind W5, enter separator through valve (W6) 14 through hole, a cross valve W3 left side, when air-conditioning is full speed at this moment, be set at 78HZ, during 12.5 amperes of stack refrigerator power outputs, be only maximum power output 90HZ, 14 amperes (outdoor be 40 ℃ set indoor be 23 ℃) are along with indoor temperature constantly descends, frequency also constantly descends, and electric current also descends, according to shown in Figure 8:

Here just owing to after room temperature control detection signal gives the CPU operation, make PWM (pulse width modulation) provide a corresponding VFC that changes the actual speed of giving motor and drawing.When refrigerator reaches predetermined temperature control, out of service.And CPU according to this blackout shut-off valve W1 after, the difference of only definite air-conditioning room temperature and design temperature is carried out rotational speed regulation and is dropped to the output refrigeration working medium of the required reality of air-conditioning smoothly compressor, power output lamp drops to on certain lattice small cup.And for example when air-conditioning be power save mode operation, promptly during 30HZ, have only 3 lamps bright.Freezer temperature control switch motion this moment, CPU opens refrigerator valve W1 according to this signal instruction follow procedure, this valve opening width and the corresponding to (see figure 9) of compressor rotary speed obtain refrigerator needs the power place of 30HZ, 400W to go out a stack number to behind the PWM, make power transistor add heavy load output, on the power indicator lamp be 5, have only and work as under the air-conditioning refrigerator situation out of service, compressor just quits work, and just can start after 3 minutes.

Point according to Fig. 9 power frequency reflects it intuitively, has become Fig. 8.We therefrom find out the power output of compressor, in time understand this operation conditions of refrigeration machine.(this point is very important for the maintenance personal) is provided with refrigerator and air conditioner in addition and heats indicator lamp (variable color diode lights) and hypnosis indication Queensland lamp, when need in the bedroom, emitting when urging the sleepy sound equipment of people, especially extremely hot summer in the room of this one drag two of 3, when being set at 23 ℃ of left and right sides, you cover the weather of bed clothes as spring and are accompanied by a burst of raindrop sound (the water outlet fruital of suitably disputing), and you are brought into beautiful dreamland.Air-conditioning is when temperature reaches 21-25 ℃ behind the SLEEP state, and (can be provided with voluntarily) sends the shower sound that the people is sunk into sleep, and just occurs in certain temperature.Increasing an IC music plate at this gets final product.

This product is mainly divided into three classes, fixed multi-door multi-functional cabinet type air-conditioning money (see figure 2) of houshold refrigerator packaged type (Figure 10,11) and office building and series types such as split-type air conditioner and refrigerator combined type, the outdoor interchanger of designing refrigerator for the convenience of the user protrudes 250mm outside refrigeratory body, to solve the air-breathing usefulness of heat extraction gas and defrosting.Different gas is to be made as the low temperature storehouse on refrigerator top in row's refrigerator, and there are three ventilation ducts (using for convection current) in the low temperature storehouse.This design is very durable in use, simple.More than control is the indication action of being sent by the defrost function controller, when room oxygen is not enough or when needing fresh air, can utilizes and protrude position income fresh air to solve the disadvantage of air-conditioning maximum.

Sometimes maintenance for convenience can be placed on top (referring to Fig. 1 dotted portion) with the part of normal maintenance such as valve, compressor.

In winter, after W3 air-conditioning cross valve changes over another state, when refrigerator needs thawed foodstuff, the switch input of thawing, compressor heats working medium to 80-90 ℃ high temperature from W3 left side mouth of pipe flow direction pipe 22, behind pressure of inspiration(Pi) control valve (W7) 18, flow into refrigerator reach in freezer 9, after the magnetic valve that thaws (W2) 10 is opened, the control valve of opening after flowing to again that thaws (W1) 17 (this valve has two functions), after the food cold air absorption in the cabinet that will thaw, 1 discharge of inflow outdoor transverter enters the right mouth of pipe of cross valve again and flows into the middle mouth of pipe, enter compressor, high temperature compressed once more.(function of suction modulation (W7) 18 is step-downs and is unlikely to disturb).

This refrigerator is set at temporarily below 6 ℃, time is more than 2 hours, refrigerator will not start (adjustable) automatically, it is according to the resistance variations of refrigerator back of the body shell heat detector and the effect of gate circuit design down, consider to enter winter, when weather enters below 6 ℃, will enter more low temperature very soon, not work be energy-conservation consideration to refrigerator like this, and the food in the refrigerating chamber also needn't continue to freeze.

When generally surpassing 8 ℃, when the refrigerator defrost, see summary figure dotted line, the compressor operating refrigeration working medium flows to 6 defrost magnetic valves (W4) 1 (this valve and W2 (10) move simultaneously) from the right pipe of cross valve W3.When hot-fluid when going into freezer compartment of refrigerator 9 and valve 18,40-50 ℃ hot working fluid melts the refrigerator frost and enters compressor in 22 mouthfuls of the inflow pipes.

Refrigerator and the air-conditioning electric control principle that moves simultaneously and put into operation respectively:

After refrigerator has a signalizing activity, this signal imports in the indoor set control circuit, indoor set can transmit the signal that a refrigerator will move and give outdoor unit, outdoor location scans with this signal whether air-conditioning is in operation, again this signal is changed into the D/A device then, make low-power level signal drive compression machine low-frequency operation, open the refrigerator refrigeration and regulate W1 and not priming chamber external fan order, bright 2 supervisors of refrigerator running indicator (blue look) output function lamp.

Air-conditioning and refrigerator paired running: when air-conditioning is firm running status, the operation of air conditioner lamp is bright, bright 7 of power signal lamp, refrigerator adds the back and gives a signal input CPU scanning, calculation learns that this machine has been to move at 78HZ, at this moment just there is an instruction to give PWM (increase 3-4 people once quickens to load as the room), make two driver control valves and motor carry out according to instruction, by making PWM output to power transistor for a signal, and it is bright to 9 lattice (can also can find by display PAG certainly) that frequency is raised to the 90HZ indicator lamp.The refrigerator room temperature thermal load that is considered as out of service reduces in this way.

Make and experiment: the frequency-adjustable speed-adjustable air-conditioning of the second-hand second generation Japan of current trend, it carries out control with a machine or four machines, and this frequency-adjustable speed-adjustable product hierarchy with many manufacturers of China at present is similar.Also have untuned only to increase electric function on the market and also claim artificial intelligence machine (Mitsubishi), and modern japan air-conditioning product has been the third generation stride into the 4th generation product, frequency-adjustable speed-adjustable fuzzy control intellectual technology, this is a kind of modern product that improves, I think that subjectively CS-G90C is the product that the Japanese third generation strode into for the 4th generation, so frequency-adjustable speed-adjustable air-conditioning ≠ frequency modulation fuzzy intelligence control technology air-conditioning, and the notion of obscuring causes fuzzy the introduction to fall behind and development.

Experimental work is prepared, and selecting the R22 refrigerator for use is ★ ★ ★ level, is equipped with 6000 yuan in 1 G90KC air-conditioning, and with music BCD250 liter, outcase of refrigerator is spent 300 yuan, and five magnetic valves and an electrical adjustment valve are spent 1000 yuan altogether.One of old window air conditioner in-room switch is spent 100 yuan, and refrigerator IC plate 87C552 spends 200 yuan, and music IC plate is spent 40 yuan.

One, a window air conditioner is placed on its refrigerator top, again two pipes of off-the-shelf 250 liters refrigerator shell are connect and weld, load onto a Pressure gauge in air-conditioning high and low pressure, the high and low pressure pipe of refrigerator respectively, under the situation of compressor non-communicated power supply, do not pour under the situation of refrigeration working medium, earlier whether test frequency-adjustable speed-adjustable fuzzy control air-conditioning normal with the last circuit control system of combining of intelligent refrigerator, program automatically controlled aspect under the normal condition, carry out second again and go on foot.

Two, the perfusion refrigeration working medium is connected with the mains compressor

(1) moves air-conditioning system earlier, whether fully after the isolated operation (comprising cooling and warming and automatically controlled regulating system) fully normally, cut off air-conditioning.

(2) start separately the operation refrigerator,, observe cooling and warming and time relation and pressure condition, the power consumption situation of no heat-insulation layer and defrosting, function ruuning situation newly such as thaw as each function fully normal (cooling and warming and automatically controlled regulating system).

(3) both move simultaneously, and natural imitation work is provided with both energy-conservation relations of working according to southern climates, as chart (4-1).

Solve the variety of issue that occurs, regulate air-conditioning high-low pressure and refrigerator high-low pressure, observe refrigeration degree and time.Independent and two situations that one are used of contrast are taken out operation dissimilarity and something in common, and solution or close to these indexs in time.

Planned time: can make under the experimental conditions, after element puts in place, of 5-8 month.

Personnel: single-chip microcomputer Application Engineer, refrigeration engineers, software engineer one.

Automatically controlled " two-in-one " empty machine test 3-5 month, perfusion working medium, motor energizing test 2-3 month.

Element source: manufacture sales orientation.

Target: fight for international big market and earn foreign exchange, the stub America and Europe introduces and buys Japanese third generation intelligence frequency modulation air-conditioner " raw material ".Make " two-in-one " " fine finishining " in a certain medium and small specialized factory of China and do finished product.Foreign exchange earning; Good with quality, purposes is wide, and cost is low, can resist the price and the class of any one tame air-conditioner or multifunctional refrigerator refrigerator and break the deadlock of household electrical appliances war.In order to fashionable, multiple functional, marketing method of high-tech innovation conversion goes to seize market.

Work it out that standard sample is confidential to be asked:

1. air-conditioning effect performance is constant substantially.

2. air-conditioning refrigerator is that " two-in-one " back will be lacked on the time in (heat) process of refrigeration.

3. refrigerator effect performance is substantially near ad eundem product data ★ ★ ★ level or overproof.

4. " two-in-one " must have breakthrough on energy consumption, can control and save both energy consumptions more than 20%.

Reason: refrigerator has intelligent frequency modulation, and heat radiation does not need resistance heated, defrost, thaws outdoor, must not starting shooting winter, (the outer mean temperature of field ice tank wall is 42 degree, and interior is-20 degree, and the temperature difference is 62 degree, now outer mean temperature is 20 degree, and extremely temperature-18 is spent, and the temperature difference is 38 degree.)

5. on production cost, controlled in both sums, about 70%.

Reason: save the cabinet of cabinet air-conditioner, do not heat the defrost element, do not want insulation material, a shared outdoor interchanger, shared computer, shared compressor, shared fluorine Lyons.

6. with the brand-new looks new product of appearance-21 century, and exceptional function, suitable valency attracts the user.

Reference: press 7000 yuan of market price music G90KC air-conditioning Dan Lengwei, the BCD250L refrigerator is 4500 a yuan/platform, and 3 is 2.2 ten thousand, Mitsubishi's 484 multifunctional refrigerators 2.8 ten thousand.

Two, as wide 550 * 606 * 1720mm of music 250L refrigerator size, refrigerating chamber 65L, refrigeration 129L, vegetables cabinet 56L." two-in-one " family style refrigerator, wide 550 * 606 * 1660mm, refrigerating chamber 30L, 35L, refrigeration 129L, vegetables cabinet 56L removes heat-insulation layer, and is short, the constancy of volume adds the high 2140mm of being of 480mm air-conditioning part, and the external form packing has so just become the same family's style shown in Figure 8 again.

More than, for general refrigerator (cabinet), air-conditioning specialized factory, production design, can make full use of current production devices, be pressed onto minimum point and the product that designs with investment, promptly main container body of outer cover and frequency modulation technology.

Below in conjunction with accompanying drawing 1, accompanying drawing 2, accompanying drawing 4 and embodiment this new invention product is discussed with further.

Enforcement 1, the purpose of this utility model are achieved by the following technical solution:

Frequency control dual-purpose air-conditioning unites two into one both exactly, totally one Compressor Technology no longer is to use respectively, as the restaurant style: its external physical characteristic is that the complete T484 Mitsubishi clamshell doors refrigerator cold-storage cabinet of Jiang Yitai removes the 400W compressor again 3,4 complete 2.44KW music cabinet air-conditioner indoor evaporator to be placed on the cold air outlet window that its refrigerator top replaces cabinet air-conditioner be 1.5, drag two split in-room switch again, each 1, totally three go out the cold air window, refrigeration is uniform effective like this, and it can use simultaneously and respectively.In addition the external form packing combines refrigerator and air-conditioning together then.(see figure 2)

Implement 2, the function temperature control of refrigerator entered on the indoor control mainboard of air-conditioning or the 87C552IC plate of refrigerator is installed in and mix an IC chip in the air conditioning chamber inner control system and make music hypnogenesis usefulness, in addition, also increase air-conditioning refrigerator cooling and warming Color-changing lamp and nine function output indicators (diode).

Implement 3, (one) be that to connect an electrical adjustment valve (W1) 17 other ends be to connect air-breathing pressure-reducing valve (W7) 18 (effect stop flow to mouthful working medium and thaw effects) from the pipe that is evaporated to dew eliminating tube 19 with one in two pipes of compressor of refrigerator excision originally particularly.Access at cross valve left side pipe to the position of air-conditioning indoor evaporator.Be on the pipeline 22.

(2) thaw winter: load onto the magnetic valve that thaws (W2) 10 between an end of the refrigerating chamber of refrigerator and the filter of refrigerator, it with (W1) 17 as the loop cold air is extracted out and to be seen the empty arrow of Fig. 1.

(3) defrost (seeing the empty arrow of accompanying drawing) is loaded onto a defrost magnetic valve (W4) 16 at air conditioning chamber's external switch inlet tube one end, it one terminates at cross valve, the other end is connected on refrigerator dew eliminating tube 15 and (W1) between 17, and it is with (W2) 10 and refrigerating chamber 9 and (W7) 18 form loops.

If slide sheet type or the unfavorable words of two-spool compressor work are adopted in above-mentioned experiment, must be refrigerator poor effect when working alone so, because rotating speed is low, working medium is few, the chamber cylinder is big and cause.So I have designed " two chambeies, one gas compressor solves " at this people's problem, promptly am produced as follows.

Enforcement 4, " two chamber one "

On former existing air-conditioning rotation scroll type compressor, axle 59 lengthenings of this end of cylinder chamber are seen Fig. 6, dotted portion; Loading onto a cylinder chamber that is complementary with refrigerator power sets up, melting is that two chambeies connect in import department, and the lumen mouth of air-conditioning is loaded onto a magnetic valve 63 (closing) and then linked to each other in the inlet tube of air-conditioning at the inlet tube 62 of refrigerator but not controlled by its valve when air-conditioning does not use.(because of check valve is arranged).Connecting use as two chambeies can't strengthen by motor load, because be frequency modulation and use electrical adjustment valve, moreover refrigerator power is very little.So needn't worry.(is appropriate but finally a compressor of air conditioner is divided into two cylinders).

Load onto when two chamber one purposes are to turn on the aircondition and can guarantee that refrigerator normally uses, refrigerator works alone when stopping air-conditioning, also can guarantee the refrigeration ideal.

Implement 5, in making 2 following family air conditioner for both refrigerator cabinets, outdoor interchanger is contained on the refrigerator, it is long that 250mm is protruded at the back, back, refrigerator cold house opened one take out different pore, discharged by ventilating fan, diagonal position is opened one to discharge orifice on before refrigerating chamber, referring to Fig. 8, they by magnetic valve 46,48 controls, generally are to take out different smell when defrost respectively, effect is than generally good, and refrigerator is decided to be not fixed like this.Key problem in technology:
